STELLER SEA LION MYSTERY

1.One of the first reasons the western stock decreased was because fishermen fished out most of the herring fish.

3.Third reason is sea lion pups are dieng because the lack of food from mothers

4.Eating pollock makes seals loose weight 401 lbs while eating herring will make you gain 450 lbs big difference.

A solution to increase the population in the western stock is to have fishermen fish a certain amount of pollock out and then to fill western stock waters with baby herring and to ban the fishing of hering and pollock fish and then add baby steller seals and adults so the populatin can be mutual.
